Chris Brown's biological father is opening up about his son's arrest, and revealing how Chris feels about Rihanna.

"He's reflecting on this situation," Clinton Brown tells People.com of his son. "He's very remorseful. He's very concerned about the situation and he wants to make sure that [Rihanna's] okay.

"This is unfortunate, this stumble, this situation," adds the 44-year-old corrections officer. "Hopefully, he will get past it. We all have our shortcomings. We all trip."

Clinton tells People.com he flew out to L.A. to attend the Grammy Awards with his 19-year-old son, whose performance was notoriously canceled after his arrest for suspicion of domestic violence; a woman had accused Chris of assaulting her the night before.

Clinton says he thinks Chris will "take from this situation and learn from it."
